EARL HENRY, OF ALBERT Lidia, liflIIfl'NEfiCTji.

To all whom it may concern:

Be it known that I, EARL HENRY, a citizen of the United States, residing at Albert Lea, in the county of Freeborn, State of Minnesota, have invented certain new and useful Improvements in Demountable Rims; and I- do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and .use the same.

This invention relates to improvements in vehicle wheels and is directed more particularly to a demountable rim for pneumatic lar nature in view, the invention consists in continuation of the slot.

the construction, combination and arrange ment of parts, set forth in and falling within the scope of the appended claims.

In he drawings: 1

Figure 1 is a side elevation of a pneumatic tire with the invention associated therewith and in collapsed position.

I Fig. 2 is a fragmentary section taken longitud inally through the rim,

Fig. 3 is a fragmentary plan view of the inner face of the rim,

Fig. 4 is a longitudinal section taken on the line 4-4: of Fig. 3, and

Fig. 5 is a transverse section taken on the line 55 of Fig. 3.

Referring now more particularly to the accompanying drawing, the rim is desig nated generally at 10 and comprises a ring, constructed preferably of springmetal, split transversely as indicated at 11. and provided with-the usual tire retaining beads 12.

One of the split portions of the ring is terminally provided with a longitudinally extending slot 13 while the material inwardly of said slot has its inner face reduced in thickness to produce a countersink 14 approximately the. width of and forming a The terminal of Specification of Letters Patent.

the other split portion of the rim has formed integrally therewith a longitudinal extension 15 and is likewise provided in its inner face with a countersink 16 corresponding to and alining with the counter-sink 1d of the first split portion. The extension 15 is adapted when the is in extended or set'up position to seat within the slot 13 of the first split portion and lie lush with the outer surface thereof relative lateral play portions being in this wise prevented.

For operating the rim to expand dr contract the same, there is provided a lever 17, hinged one end to the second. split portion as indicated at 18' and normally seated in the alined counter-sinks id and 16 to lie flush with the inner face of the ring, it being of course understood that said lever is of arc-shaped fm'n'iation so as to conform to the curvature of the ring. Engaged tran versely through the rim and slot adjacent the closed end of the latter'is a pin 19 on which is intermediately pivoted the lever-17. Thus by grasping the free end of the lever and swinging the same inwardly on the hin e 18. the first solit ort-ion of the rin l a a will be sprung inwardly and the ring thus contracted to permit of its disengagement from the .tire, the extension 15 moving out of the slot 13 as is obvious.

In order to further assist in locking the split portions of the ring in longitudinal alinement and relieve any strain which might be brought upon the points of attachment of the lever "with the ring. the free end of the first split portion at each side of the slot 13 is reduced in thiclniess for a portion of its length indicated at 20 and provided with apertures 21 for engagement with corresponding lugs 22 carried by the second split portion; said. latter portion being also reduced in thickness as indicated at 23 to accommodate the reduced portion 20.

The lever l? is also provided at each side of the vpin 19 with apertures 24* engageahle with lugs 25 on the split portions whereby to provide additional safeguard against relative lateral or longitudinal movement of the split portions.

What is claimed is l. A. deimnintahle rim comprising a split ring n one and provided at its other end it extension cngageable in the slot, and a lever hinged at one end adjacent the extension andpivoted in the slot to expand or contract the ring.
